Abstract: The rheological behavior of whole and centrifuged mango (Mangifera indica L. var. Keitt) and pineapple (Ananas comusus L. merr var Perola) pulps was analysed at 30 degreesC, in a rotational viscometer Haake Rotovisco RV-20. The experiments were conducted with measuring system of 45 mm diameter parallel plates (PQ45) with gap of 0.5 mm, at shear rates up to 874 s(-1). The rheograms were fitted with Casson, Ostivald-of-Waelle and Mizrahi-Berk (M-B) models. The Brix of pineapple and mango pulps were 16.6 and 13.3 degreesBrix, respectively, and the insoluble solids content was 0.108 g/kg for mango and 0.054 g/kg for pineapple. The best adjustment was obtained with M-B model. It was observed that the pulps presented pseudoplastic behavior, and the suspended solids had great influence on the consistency index.
